A new study has claimed that hardened blood vessels in the brain, and oxygen-starved brain tissue cause insomnia in adults.
The researchers also warned that these issues may contribute to a greater risk of stroke and cognitive impairment.
Study author Dr. Andrew Lim, a neurologist and scientist at Sunnybrook Health Sciences Center in Toronto said “The forms of brain injury that we observed are important because they may not only contribute to the risk of stroke but also to chronic progressive cognitive and motor impairment.
“However, there were gaps in what we knew about underlying brain changes that may link sleep fragmentation with these neurological outcomes.”
The study observed the brains of 315 people who underwent autopsies after they died. The people were 90 years old, on average, when they died, and 70 percent were women.
